300C, Magnum RT & Charger RT (5.7L V8)
My buddy asked me a question that I'm not technically inclined to answer. He has a 2012 Ram pickup with a 5.7 Hemi. Has new coil, new injector, new spark plugs. Performed compression test run and it has a 150 psi. It does not skip on idle or at Cruise speed only under acceleration. Any help...
